Waste and vent pipes



Jan. 28, 1969 F. M. DIRKs WASTE AND VENT PIPES Filed June 13, 1966'United States Patent Oh 3,423,771 WASTE AND VENT PIPES Francis M. Dirks,604 S. Cloudas Ave., Sioux Falls, S. Dak. 57103 Filed June 13, 1966,Ser. No. 557,252 U.S. Cl. 4-211 Int. Cl. E03d 9/04 2 Claims ABSTRACT FTHE DISCLOSURE The invention relates to a single waste and vent pipe Thepresent invention relates to waste and vent pipes and more particularlyto a vertical Waste and vent pipe adapted to be installed Iwithin thewall of a house, the wall being constructed of conventionalstudding.'Addi tionally, the Iwaste and vent pipe is of a length anddiameter such that connections to the usual fixtures appurtenant todwellings can be readily made within the space conforming toconventional stud dimensions. Specifically the waste and Vent pipe isone formed from cast iron or other inexpensive materials and hassanitary tapped bosses for suitable connection with basins, sinks, bathtubs, wall hung Water closets, and the like.

Most plumbing codes, including that of the Federal HousingAdministration and National Plumbing Code require a three-inch mainvent. lf tttings are required in a space limited by a four-inch Iwidestud it would be necessary to furr out the Iwall to accommodate thecouplings or littings since the diameter of the latter would necessitateadditional space. Furthermore, walls of extra thickness require theinstallation of special door jambs. It is, therefore, an object of thisinvention to provide a waste and vent pipe of suiiicient length toextend below the iioor of a room as well as above the ceiling toeliminate the use of couplings or fittings in the Wall between theceiling and the floor. At the same time the waste and vent pipe istapped at such distances from its ends that threaded connections can bemade with the iixtures previously mentioned.

Other objects of the invention will be appreciated from the followingdescription taken with the accompanying drawings in which:

FIG. 1 is an elevation `of a dwelling, partly in section, illustratingthe manner in which a preferred embodiment of the 'waste and vent pipeis installed; and

PIG. 2 is a front rview of a modified form with -hub end of the wasteand Vent pipe shown in FIG. l.

Referring to the drawings, the dwelling comprises the usual basement.11, lloor 12, ceiling 13, and roof 14. The side walls include theconventional 2" x 4 studding 15. The novel 'waste and vent pipe, shownat 1-6, is of substantially constant diameter and of such length that itextends below the lloor 12 and above the ceiling 13.

3,423,771 Patented Jan. 28, 1969 Lice Disposed between the ends of thewaste and vent pipe are sanitary side apertures 17, 18, 19, and 20, eachof which is tapped to provide threaded connections with drain pipesleading to lwash basins 21, 22, 23, and bath tub 24, respectively. Thelwaste and vent pipe is provided With these apertures during formationthereof since plumbing codes prohibit drilling and/or Welding before orafter installation of the vent pipe, cast iron having a tendency tocrack or split due to uneven heating at localized points or to excessivecutting as by drilling.

IIn FIG. 1, the upper end of the 'waste and vent pipe is threaded at 25to receive fittings or an axially aligned extension 26, the latterhaving its outlet exterior of the dwelling and being of a greaterdiameter than that of pipe 16 for the reason that in certain localitiesthe extension must be lar-ge enough to prevent frost formation suicientto choke the vent.

In FIG. 2, the upper end of the Waste and vent pipe is provided with ahub bell-shaped enlargement 27 to accommodate the extension. Also thetapped opening 17 for vent connection to fixture 21 is located 42 abovethe floor.

Since basement walls are usually unfinished and studding is, therefore,not required, the lower end of the vent pipe 16 projects only a shortdistance below the floor 12. Hence, connection of this end can be maderwith the hub of an ordinary soil slitting or pipe 28 intoy whichdrainage from water closet drain pipe 29 is permitted to flow.

While the waste and vent pipe is illustrated as having four sanitarytapped openings, it is intended that more or fewer openings may beprovided if found necessary. The invention is, therefore, subject tosuch modiiications as fall lwithin the scope of the appended claims.

What is claimed is:

1. A vertical Iwaste and 1vent pipe adapted for installation in a wallsupported by studding disposed between spaced flooring and a ceiling,one end of said waste and vent pipe extending below said flooring, theopposite end of said waste and vent pipe extending above said ceiling,the diameter of said lwaste and vent pipe being substantially constantbetween its ends, said diameter being less than the larger width of saidstudding, said waste and vent pipe being provided with a plurality ofhorizontally directed threaded openings for attachment to and in axialalignment with horizontal drain and vent pipes associated with xtures,said openings being disposed in the sides of said waste and vent pipe ina common vertical plane, said horizontal pipes being parallel to saidwall.

2. A waste and vent pipe as defined in claim 1 in 'which means areprovided at the upper end of the pipe for attachment to a vent extensionmember.
